An international team of researchers, led by Shuowen Jin of the Technical University of Denmark, has discovered a huge cosmic structure called the “Cosmic Vine”. This discovery, detailed in an article on the pre-print server arXiv, reveals a structure 13 million light years away, made up of at least 20 massive galaxies.

Colorful composite image of the Cosmic Vine The Cosmic Vine, detected in the Extended Groth Strip (EGS) field observed by the JWST (James Webb Space Telescope), is a structure of galaxies 13.04 million light years long and 0.65 million light years wide million (One million (1,000,000) is the natural number following nine hundred and ninety-nine…). Its total mass is estimated at 260 billion solar masses, including six galaxy overdensities. These characteristics make it significantly larger than other groups of compact galaxies and proto-clusters at redshifts greater than 3.0.

The study highlights the existence of two massive galaxies within this structure, designated Galaxie (Galaxies is a quarterly French journal devoted to science fiction. With…) A and Galaxie (A galaxy is, in cosmology , an assemblage of stars, gas, dust and…) E. Surprisingly, these galaxies are quiescent, with star formation rates below 0.5 solar masses (In astrophysics, solar mass is the unit of mass conventionally used for…) per year, and have morphologies dominated by bulbs. The researchers suggest that these galaxies may have been inhibited by bursts of star formation triggered by mergers or feedback from an active galactic nucleus (AGN) around 500 million years ago.

According to the article, the Cosmic Vine is not yet a virialized system (tending towards a dynamic equilibrium), it is in the process of forming a cluster of galaxies. The study highlights the possibility that Galaxy E might become the brightest galaxy if it moves toward the cluster’s core in the future.

This discovery paves the way for new research on quiescent cluster galaxies at high redshifts, essential for understanding the formation and evolution of the largest structures in the Universe. With the recent launch of ESA’s Euclid space telescope, focused on exploration, intention to discover something unknown.) of the structure and history of the cosmic web, such research might prove fruitful.
